1. Six easy steps to a great vocal recording
1 No matter how basic your gear, the fundamental techniques of vocal recording apply, so grab your mic – and don’t forget the pop filter – and plug it into the mic input on your audio interface. Turn on phantom power (possibly labelled 48V) if your mic needs it. Like the other audio interface controls in this tutorial, this could be a physical switch or a software setting.
2 Now let’s set the input recording level or gain. If the signal level is too quiet, you’ll have to raise the recording level, which will make background noise louder too – especially noticeable once effects like compression and distortion are added. If the gain is too high, it’ll overload the input and distort. Around 12dB of headroom between the loudest peaks and the top of the wave display (0dB) is a good aim.
3 The distance from mouth to mic makes a huge difference. From 2 metres, we get lots of room ambience, and there’s audible background noise when we turn the signal up to a usable level. At half a metre, we get a natural ‘close-by’ sound, with some room sound. At a few inches, the proximity effect gives rich bass, and there’s minimal room sound. Experiment until you find the sound you want.
4 Microphones pick up all kinds of sub bass rumble that is nothing to do with the vocal, so recordings are routinely high-pass filtered at around 75Hz. You can apply a filter plugin after recording, but some mics and interfaces have such a filter built in – it’s a good idea to use these if you have them as removing the bass before it hits the interface’s converters means less chance of distortion.
5 When recording to a backing track, use headphones so that the monitor speakers don’t bleed back into the mic. When monitoring through your DAW, if there seems to be a short delay between speaking and hearing yourself through the ‘phones, reduce the buffer size and remove any latency-inducing plugins. Alternatively, use the direct monitoring feature that some audio interfaces have.
6 When processing vocals creatively, we often use processes like heavy compression and distortion, which can bring the level of background noise up considerably. If your recording is noisy, try a noise gate, or manually cut the parts where there’s only background noise. If that’s not enough, try a noise reduction tool like the one in the free Audacity.
